Tallysman TW4721/TW4722 Wideband GNSS Antenna

TW4721/TW4722  is a Wideband Dual Feed GPS/GLONASS/BeiDou/Galileo Antenna

The Tallysman TW4721/Tw4721 is a compact, wideband GNSS antenna that provides accurate reception for all upper L- band GPS, GLONASS, Beidou, and Galileo signals (L1, G1, B1, B1 BOC, B12, E1) and associated augmentation signals (WAAS, EGNOS and MSAS SBAS). It offers circular response over its entire bandwidth, thereby producing superior multipath signal rejection resulting in higher accuracy of position and time. This antenna employs Tallysman’s patented Accutenna® technology.

The TW4722 is pre-filtered, the TW4721 is not. Please contact us for specifics.
